CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 600,275, dated March 8,1898.

Application filed June 2, 1897. Serial No. 639,109. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL M. ADAMS, a citizen of the United States,residing at Powhatan, in the county of Brown and State of Kansas, haveinvented new and useful Improvements in Cultivators, of which thefollowing is a specification.

This invention relates to a new and improved cultivator, its objectbeing to cultivate two rows at one time. It is adapted to be drawn bythree horses and guided by one person. The operating mechanism issupported on a sled the runners of which are made adjustable to suit thedistance between the rows or furrows.

The adaptation of runners to my cultivator enables same to be drawn withbut little exertion on the part of the animal and provides for itsoperation in marshy as well as other soils.

My invention will be readily understood by referring to the accompanyingdrawings,

wherein-- Figure 1 is a perspective view of the machine complete. Fig. 2is a side elevation of the machine with cultivators raised, as forhousing or transportation. Fig. 3 is a perspective view of one of theadjustable rests for the cultivator-frames, and Fig. 4 a like View of aswivel-pin for receiving one of the handles.

Referring again to the drawings, the letters A A designate thesled-runners, B a connectin g front bar or board, and O the connectingrear board. The front and rear boards may each be provided with a seriesof boltholes to permit of the runners being secured thereto at variabledistances apart.

The upper part of each runner is provided near its forward end with aseries of perforations d d, to either of which the rear ends of staplesand connecting-devises determines the side orswinging motion of thecultivatorframes.

The aforesaid frames are each composed of a front bar Z, to the ends ofwhich are socured the rearwardly-projecting side bars m m. These bars 'mm are inclined toward each other and have their rear ends connected withthe front bar Z by means of brace rods or bars n n.

The shanks 0 0' of the shovels p p are adapted to be connected with theside bars m m of the cultivator-frames by means of bolts (1 q and beheld in adjusted positions by means of the semicircular pieces M, whichare provided with perforations for the reception of bolts or pins,whereby the shovels are held at such angles as the operator may deembest for the successful working of the machine.

The cultivator-frames are guided and their rear ends held at any desiredelevation by the handle-bars S S, which are connected with thecultivator-frames by the bars or rods it. The front ends of thehandle-bars are connected with the upper edge of the rear board 0 bymeans of swivel-pins, as shown at u a in Fig. 1.

The letters V V designate end rests for the front bar of thecultivator-frames. These rests consist of vertical plates of metal, eachprovided with a vertical slot 22 for the passage of a bolt '1), wherebyit is secured to the board 0 at any desired height. The lower end ofeach rest is provided with a rearward projection to for the support ofthe cultivator-frame, and the upper part of the device is formed into anoblate hook to to engage the upper edge of the backboard O, the saidedge being provided at such place with a mortise or a mortised block tofor the reception of the same.

Particular attention is directed to the facts that the front shovels ofmy cultivators are at a greater distance from the plants than the rearshovels and that the rests hold the cu1tiva-.

tor-frames in horizontal positions and prevent any rolling or rocking ofthe same when operating on uneven ground. Attention is also called tothe fact that the sled-runners operate between two rows of plants, whilethe cultivators proper straddle the same. The person in charge walksbetween the rows and the shovels of each half of cultivator-frameoperate against one side of each row.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. The combination in a cultivator, of a sled having runners adapted tostraddle two rows;

, and cultivator-frames of triangular form, the

base of each triangle being centrally connected with the rear of thesled-frame by a swivel-joint, a handle-bar pivotally connected with therear of the sled-frame, and rods connecting the said handle-bar and therear of the cultivator-frame, substantially as an for the purpose setforth.

2. The combination in a cultivator, of a pair of runners, a connectingfront board and a SAMUEL M. ADAMS.
